Cook-Swartz Doppler Probe Surveillance for Free Flaps-Defining Pros and Cons.

Introduction The main postoperative complication of free flaps is perfusion compromise. Urgent intervention is critical to increase the chances of flap survival. Invasive flap perfusion monitoring with direct blood flow feedback through the Cook-Swartz Doppler probe could enable earlier detection of perfusion complications. Materials and Methods Between 2012 and 2016, 35 patients underwent breast reconstruction or defect coverage after trauma with a deep inferior epigastric perforator, anterolateral thigh, transverse musculocutaneous gracilis, gracilis, or latissimus dorsi flap in our department. All flaps were monitored with a Cook-Swartz probe for 10 days postoperatively. The 20 MHz probe was placed around the arterial-venous anastomosis. A flap monitoring protocol was established for standardized surveillance of postoperative perfusion. In the event of probe signal loss, immediate surgical revision was initiated. Results Signal loss was detected in 8 of the 35 cases. On return to the operating room, six were found to be true positives (relevant disruption of flap perfusion) and two were false positives (due to Doppler probe displacement). There were also two false negatives, resulting in a slowly progressive partial flap loss. Flap perfusion was restored in three of the six cases (50%) identified by the probe. Following surgical intervention, three of the six cases had persistent problems with perfusion, resulting in two total flap losses and one partial flap necrosis leading to an overall 5.7% total flap loss. Conclusion Postoperative flap perfusion surveillance is a complex matter. Surgical experience is often helpful but not always reliable. The costs, false-positive, and false-negative rates associated with invasive perfusion monitoring with Cook-Swartz probe make it most appropriate for buried flaps.

Risk Factors for Complications after Skin-Sparing and Nipple-Sparing Mastectomy.

INTRODUCTION: In order to achieve a complication-free breast reconstruction, it is fundamental for each individual patient case to determine preoperatively certain risk factors that might have a negative impact on the postoperative result after skin-sparing (SSM) or nipple-sparing mastectomy (NSM). METHODS: A retrospective study of 39 female breast cancer patients who received SSM or NSM breast reconstruction in our department (time interval: 2010-2015), was performed. The study focus is on determining patient characteristics (e.g., demographics, history of radiotherapy/chemotherapy, menopausal status, amount of resected breast tissue) leading to higher complication rates. RESULTS: Overall, 50 mastectomies (27 SSM and 23 NSM) with 6 immediate and 35 immediate 2-stage tissue expander breast reconstructions amounting to a total of 41 surgical interventions (n = 41) were carried out. Median follow-up time was 2 years and 5 months (range 121-1,863 days). Increased complication rates were associated with the following patient characteristics: age >50 years (p < 0.05) and personal history of cardiovascular disease (p < 0.05). Increased but not significant risk factors included postmenopausal status (p = 0.07), radiotherapy prior to SSM/NSM (p = 0.06), and weight of resected breast tissue >438 g (p = 0.09). CONCLUSION: This work identified age >50 years and personal history of cardiovascular disease to be risk factors for increased complication rates following SSM and NSM. Therefore, the given findings should be taken into account when selecting patients for these 2 procedures.

Functional Reconstruction with Latissimus Dorsi Flap following Resection of an Extensive Basal Cell Carcinoma in the Shoulder Region: A Case Report.

Large and ulcerating skin tumors have become a rarity in the modern Western world. However, these conditions can cause serious life-threatening complications. The case of a 60-year-old male Caucasian patient is reported, who had suffered from an extensive basal cell carcinoma in the right shoulder region for several years. The patient kept the lesion secret from his friends and family and delayed presentation to health care services. After an episode of tumor-related heavy bleeding, the patient was referred to our clinic and received a radical surgical tumor resection-followed by defect coverage with a latissimus dorsi myocutaneous flap. An alternative treatment option that could be offered to the patient would have been a mutilating surgical procedure with an arm amputation. By using this plastic reconstructive surgical technique, the main function of the shoulder joint was conserved. The presented case demonstrates options for defect coverage of problematic wounds in anatomically complex body regions-like the shoulder-by using a functional reconstruction using myocutaneous flaps.

Risk factors for lymph node metastasis in early gastric cancer patients: Report from Eastern Europe country- Lithuania.

BACKGROUND: Current risk factors for lymph node metastasis in early gastric cancer have been primarily determined in Asian countries; however their applicability to Western nations is under discussion. The aim of our study was to identify risk factors associated with lymph node metastasis in Western cohort patients from the Eastern European country - Lithuania. METHODS: A total of 218 patients who underwent open gastrectomy for early gastric cancer were included in this retrospective study. After histolopathological examination, risk factors for lymph node metastasis were evaluated. Overall survival was evaluated and factors associated with long-term outcomes were analyzed. RESULTS: Lymph node metastases were present in 19.7% of early gastric cancer cases. The rates were 5/99 (4.95%) for pT1a tumors and 38/119 (31.9%) for pT1b tumors. Submucosal tumor invasion, lymphovascular invasion, and high grade tumor differentiation were identified as independent risk factors for lymph node metastasis. Submucosal tumor invasion and lymphovascular invasion were also associated with worse 5-year survival results. CONCLUSION: Our study established submucosal tumor invasion, lymphovascular invasion, and high grade tumor differentiation as risk factors for lymph node metastasis.

Age, Sex, Body Mass Index, Education, and Social Support Influence Functional Results After Total Knee Arthroplasty.

INTRODUCTION: Total knee arthroplasty (TKA) is an effective treatment for knee osteoarthritis. Patient-reported outcome after TKA is influenced by multiple patient-related factors. The aim of this study was to prospectively evaluate preoperative patient-related factors and to compare the self-reported outcomes 1 year after TKA among groups differing by age, sex, body mass index (BMI), education, and social support level. METHODS: 314 patients, who underwent TKA in Vilnius Republican University Hospital between the end of 2012 and the middle of 2014, were included in a study. The preoperative and 12-month follow-up measurements were obtained using Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Short Form-12 (SF-12). Differences between patient groups according to gender, age, BMI, level of education, and level of social support were analyzed. RESULTS: At 12-month follow-up men demonstrated better results than women in WOMAC (P = .003) and SF-12 both domains (P < .05). Patients with a higher social support demonstrated higher scores in physical function according to SF-12 (P = .008). Better preoperative WOMAC and SF-12 scores were a predictor of better outcome 1 year after surgery. There was no difference in postoperative scores in different age, BMI, and education groups according to WOMAC and SF-12. CONCLUSION: There is no difference in self-reported functional outcome between patient groups differing in age, BMI, and education. Men and socially supported patients demonstrate better postoperative functional results 12 months after TKA. Better preoperative knee function and overall physical and mental function are predictors of better outcome 1 year after TKA. Age and obesity should not be limiting factors when considering who should receive this surgery.
